Fading LED with 555 Timer

Phewwww Finally it worked!! “Successs!!!” (Dexter’s style) I used arduino and it was too easy to just control the Brightness of LED by simply putting in numbers in code lolo I started looking on google a circuit to make LED fade up/down using 555 timer, i found lots of circuits but LED used to fade…

I started looking on google a circuit to make LED fade up/down using 555 timer, i found lots of circuits but LED used to fade up but did not do a periodical up and down fading
or if it was fading it was too fast…

i kept on changing my resistor values and finally it came up 😀

so look at my paintbrush made circuit and grab the values and play with it 😉

Good Luck !!!
